Chambered exhaust was not listed on factory documentation because it was standard equipment on L34, L78 and Z/28 until December 4, 1968. Date is from the recall letter sent to owners, not the TSB.
In the May '69 issue of Hot Rod there is a photo of the installation of 5.38 gears. The chambered rear mufflers are seen in the photo.
